Auxiliary Tank

Matt,

Thank you.

When the city boiler inspector inspected my 4 tanks he used an ultrasonic gadget to check the thickness of the bottom and walls of the tanks. I was worried about the 150gal tank as it was an antique but it always came out fine. Just another permit the city could soak us for every 3 years and a copy had to be on every air storage tank.

What material would you run the air distribution in the garage? Pipe, tube size?

Look up "Rapid Air"  They offer a full line of airline supplies.  I installed one of their kits in my garage a few months back.  The only air leakage I get is from the tapered threaded connections.  I know what caused the leakages and it wasn't an issue with the Rapid air equipment.

I would probably run a 3/4" or 1" line between tanks using their PEX tubing.

"Firestopper" Paco, has a very nice Rapid air system in his shop.  Maybe he can tune in and share his experience.

Sizing mostly depends on required airflow and length of run. Elbows and Tees also figure into it.

An engineer at work described for me the safe way to do a hydro test on a tank at home a few weeks back and it sounded very safe to me. As I recall he told me to fill the tank with water and leave just a little free space to create pressure. As I recall he told me to put a gauge in there somewhere (this is all memory, no notes) then pressurize. If it blows full of water it is much less hazardous. Sorry I do not recall more of the specifics.

UB, you don't have to leave any air in the tank, but you more than likely will have some trapped air.  Be ideal to place a pressure gage on one of the fittings, but not a have to. 

What ever you do, have a length of hose from the pump to the tank and a safe place to get behind.  No fun getting hit by pressurized water if it burps.

I've done lots of high pressure testing over the years under controlled conditions with water, oil, and nitrogen gas.  You can never be safe enough.  And I have split 9-5/8" OD casing/pipe at 10,000 psi with 350 degrees on the test cell.  Lets just say, things get real excited real quick!

I use to hydro test gas pipelines, and used that knowledge to test a 60 gallon tank for myself, and an 80 gal. for Tony Wells.
I can post some pictures if interested.

Please do.

I will get a post put together soon.

I hydro boilers, feed tanks, da tanks, air tanks and piping all the time, all work related. We have standardized forms to fill out, with all of the required data.
